Specifications

The Choice of Submersible Motor Pump:The followig content should be understood in order to choose and operate submersible motor pump correctly:1 Understanding all clauses mentioned in operation conditions2 Pay attention to the diameter and the depth of well3 Pay attention to the static water level and the flowing water level of well4 Pay attention to the water surging capacity of the wellThe capacity,head,and the diameter of full set should be shosen according to the water surging capacity,the depth and the diameter of well.The water surging capacity of well should meet the requirement of the capacity of submersible motor pump,so that the submersible motor pump can be under the water totally when it works.

Working conditions:

1. 380V (deviation≤5%), 50Hz (deviation≤1%), 3 phases

2.Electric motor must be full of clean water

3.The first piece of impeller of pump should be at least 2m or more below dynamic water level. The distance from Pump to static water level should be not more than 70m. The distance from motor base to well bottom should be not less than 3m.

4.Water temperature should be not more than 20℃

5.Sand content of water (based on mass of sand) should be not more than 0.01%

6.PH should be 6.5-8.5

7.The content of hydrogen sulfide in water should be not more than 1.5mg/l

8.The content of chloride ions should be not more than 400mg/l

9.Water yield of water source should satisfy the demand of pump running.
